My new wheels on my truck {pic} and questions...

I finally got my 2010 Nissan 18" wheels mounted. I wanted a bigger profile wheel for the rear, however I want it to sit up under the fender a little more.
The bed is gutted so there is no interference problems with the wheel scrapping anything. I have already installed 3" drop blocks as well as removing all, but two leaf springs. But, it still needs just a bit more. I just bought the tires, so I don't want to go with smaller tires.

Looks like the only way would be coilovers, 3" inches is the most you can do with drop blocks, correct?

they make 4" drop blocks. i had them on my old mazda for a year or so. or you can keep your 3" ones and remove a leaf spring

i got 4" drop blocks but those look great on the truck
